Flexible hose wound of a web material and reinforced with wire windings

Abstract

The invention relates to a flexible hose formed of a wound web material and having its walls reinforced by wire windings, with the edges of successive web windings overlapping one another. In accordance with the invention, the longitudinal axes (Da) of the wires (13, 13', 13") and the longitudinal axis (ba) of the web material (3) extend at equal inclination with respect to the hose axis (A), and the reinforcement consists of at least two wire windings.

I claim: 
     
       1. A flexible hose wound of a constantwidth web material with overlapping edges of successive windings and reinforced with windings of a wire material affixed to the interior surface of the web material, said wire material comprising at least two juxtaposed wire coils having the same pitch as the wound web, one of the coils being embedded between the overlapped edges of successive web windings and at least one of the coils being spaced from the overlapped edges of successive web windings and engaged with only one web material winding. 
     
     
       2. A hose according to claim 1, said windings of the wire coils being disposed symmetrically with respect to center lines drawn through the web windings. 
     
     
       3. A hose according to any of claims 1 or 2, characterized in that the pitch angle of the wire coils is 2° to 20°.
